Amazon Aurora is a PostgreSQL compatible relational database built for the cloud, that combines the performance and availability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases.

It delivers up to three times the throughput of standard PostgreSQL. Amazon Aurora is designed to be compatible with PostgreSQL, so that existing applications and tools can run without requiring modification. It is available through Amazon Relational Database Service (RDS), freeing you from time-consuming administrative tasks such as provisioning, patching, backup, recovery, failure detection, and repair.

Amazon Aurora is designed to offer greater than 99.99% availability, increasing PostgreSQL performance and availability by tightly integrating the database engine with an SSD-backed virtualized storage layer purpose-built for database workloads. Amazon Aurora's storage is fault-tolerant and self-healing, and disk failures are repaired in the background without loss of database availability. Amazon Aurora is designed to automatically detect database crashes and restart without the need for crash recovery or to rebuild the database cache. If the entire instance fails, Amazon Aurora will automatically fail over to one of up to 15 read replicas.

You can quickly launch an Amazon Aurora database instance with a few clicks in the RDS Management Console. Amazon Aurora scales storage automatically, growing storage and rebalancing I/Os to provide consistent performance without the need for over-provisioning. For example, you can start with a database of 10GB and have it automatically grow up to 64TB without requiring availability disruptions to resize or restripe data.

Amazon RDS makes it easy to set up, operate, and scale PostgreSQL deployments in the cloud. With Amazon RDS, you can deploy scalable PostgreSQL deployments in minutes with cost-efficient and resizable hardware capacity. Amazon RDS manages complex and time-consuming administrative tasks such as PostgreSQL software installation and upgrades; storage management; replication for high availability and read throughput; and backups for disaster recovery.

With just a few clicks in the AWS Management Console, you can deploy a PostgreSQL database with automatically configured database parameters for optimal performance. Amazon RDS for PostgreSQL database instances can be provisioned with either standard storage or Provisioned IOPS storage. Once provisioned, you can scale from 5GB to 3TB of storage and from 1,000 IOPS to 30,000 IOPS. Amazon RDS for PostgreSQL also enables you to scale out beyond the capacity of a single database deployment for read-heavy database workloads.
Over the past few years, PostgreSQL has become the preferred open source relational database for many enterprise developers and start-ups, powering leading geospatial and mobile applications. Amazon RDS for PostgreSQL gives you access to the capabilities of a familiar PostgreSQL database engine. This means that the code, applications, and tools you already use today with your existing databases can be used with Amazon RDS.

Mammoth PostgreSQL + Replication, is 100% pure PostgreSQL with integrated replication. Written in pure C, the Mammoth PostgreSQL + Replication is a powerful addition to the Command Prompt PostgreSQL line of products. It is designed specifically with reliability in mind and it works with the Open Source and Command Prompt versions of PostgreSQL. Mammoth PostgreSQL + Replication supports asynchronous replication and is designed to be WAN tolerant.

Postgres Plus Advanced Server is an enterprise ready database renowned for its transaction processing capabilities and exceptional performance across a spectrum of query intensive and mixed load applications.

Built upon PostgreSQL, the world's most advanced open source database, Advanced Server v8.3 Release 2 offers deeper Oracle® compatibility to more applications than ever before, as well as performance and scalability features like Infinite Cache that are not available in the community version of PostgreSQL.

VMware vFabric Postgres is a VMware-optimized relational SQL database. vFabric Postgres is fully compatible with open source PostgreSQL, enabling customers to leverage existing standard PostgreSQL tools. vFabric Postgres comes in a virtual appliance and also as Linux RPM packages. It has virtualization optimizations such as elastic database memory to share database memory pools and smart configuration to reduce tuning time after resizing virtual machines.
The changes to core PostgreSQL are also open sourced under PostgreSQL license and is available on the product download page.
